High-Q transmission characteristics in terahertz guided-mode magnetic resonance system
نویسندگان
چکیده
Introduction: Guided mode resonance is generated by coupling wave diffractions with the waveguided mode. The guided resonances provide narrow-linewidth and intensity for high quality factor (Q-factor) optical resonators. Methods: we demonstrate high-Q propagating on a low-loss, terahertz guided-mode magnetic system, which are periodic square lattices of U-shaped split ring resonators (SRRs) quartz substrates. Results: By choosing judicious array period, two distinct frequency dipole Q-factor observed. interaction at similar frequencies produces total transmission peak. Discussion: dependences lattice period structural parameters investigated discussed. difference between these widens increasing Lattice period. sharp spectral feature each results in abrupt degradation edge transmission. proposed scheme promising efficient THz sensing, switching, slow-light devices.

Resonant dipole nanoantennas promise to considerably improve the capabilities of terahertz spectroscopy, offering the possibility of increasing its sensitivity through local field enhancement, while in principle allowing unprecedented spatial resolutions, well below the diffraction limit. Here, we investigate the resonance properties of ordered arrays of terahertz dipole nanoantennas, both expe...
